A-QUIZ. (15 marks) Attempt the Assignment 2 quiz after Week 9, and paste the Moodle summary of your result below.
**** Paste your result here ****
B-Q1. 15 marks (3 x 5 marks = 15 marks)) Digital Logic and Design:
a) Construct the following digital circuit with Logisim. The circuit has two outputs S and T and three inputs A, B and C.
S = A/BC + /ABC + AB/C + /A/B/C
T = /A/BC + A/BC + /AB/C + ABC
b) Generate the truth table using Logisim for inputs A, B and C and for outputs S and T.

c) Verify that the circuit you developed can be used as a 3-bit adder (Full adder) i.e., A and B are the two bits to be added and C is is the Carry-in bit. S is the sum of A and B and T is the carry-out bit.

B-Q2 10 marks (2 x 5 marks = 10 marks) Perform the following operations:
a) Convert the decimal -95.375 to IEEE 754 32-bit format. Show all the working.
b) Convert the following IEEE754 32-bit floating-point representation into decimal: 42AE4000. Show all the working.
B-Q3. 10 marks (5 x 2 Marks = 10 marks)
